WATERPROOF rocizn'r.

Application filed March 16, 1328. Serial No. 262,192.

This invention relates to waterproof pockets and has for its object toprovide a novel waterproof pocket which can be worn by bathers ana inwhich various articles such as matches, cigarettes, powder puffs, etc.may be lrept in a perfectly dry condition.

The features wherein my invention resides will be more fully hereinafterset forth and then pointed out inthe appended claims.

In the drawings wherein I have illustrated a selected embodiment of myinvention, Fig. 1 is a fragment-ary view illustrating the manner inwhich my improved pocket may be used.

Fig. 2 is a perspective view of the pocket showing 1t open;

Fig. 3 is a rear side view of the pocket;

Fig. 4 is a horizontal section taken on substantially the line 4-4, Fig.6 showing the pocket partially closed;

Fig. 5 is a similar view showing the pocket entirely closed;

Fig. 6 is a section'on the line 6-6, Fig. 5;

Fig. 7 is a section on the line 7-7, Fig. 5.

My improved pocket comprises a pocket member lwhich is made ofwaterproof material and which is shown as open at the top 2. Anysuitablewaterproof material may be used for making the pocket member but I willpreferably employ rubber for this purpose as this is not only waterproofbut also more or less elastic.

rlhe openend 2 of the pocket member is adapted tol be closed in awaterproof man# ner throughthe medium of two clamping members 3 and 4which are attached to the two opposite sides 5 and 6 of the pocketmember.

The clamping member 4 is a strip of resilient material which is shown asriveted or otherwise secured to the side 5 of the pocket by meansoofsuitable rivets 7 The clamping' member 3 is also preferably made ofmetal and is secured to the side 6 of the pocket Vby rivets 12. The twoclamping strips are so constructed that they may be detachably securedtogether at eachend and when they are attached together the upperl edgesof thesides 5 and 6 of the pocketiwill be tightly clamped between themin a manner to make a water tight joint. y

As herein shown one end of the clamping strip 4 is provided with the lip8 under which the end 9 of the clamping strip 3 is adapted to be enteredas shown in Fig. 4. The opposite end of the clamping member y4 isprovided with a spring catch 1() which is adapted to latch over the end11 of the clamping member 3 thereby to hold the two clamping members inclosed or clamping relation. i

I have stated abovethat the clamping member 4 was a curved member and itis so arranged that its convex face is'directed toward the clampingmember 3. The clamping rmember 3 may be straight or if curved itscurvature will be on a greater radius than the normal curvature of `1dieclamping member 4. Said member 3 is also stiffer and less resilient thanthe member 4. Consequently when the end 9 of the clamping member 3 isinsertedl underneath the lip 8, as shown in Fig. 4, and then the twoclamp' ing members are closed together and the end 11 of the clampingmember 3 is forced past the catch 10 the` member 4 will be. straightenedsomewhat and its resiliency will serve to apply afiirmclamping pressureto the upper portions 5, 6 of the pocket.

The clamping member 3 is herein shown as connected tothe side 6 ofthevpoclret member by means of suitable rivets 12 and said member isprovided at its upper edge with the flange 13 which overlies thetopjedge of the member 4` when the clamping members are closed together.The clamping member 3 is alsoshown as covered or enclosed in acasing 14of rubber or some other similaryielding material and thus when the twoparts are clamped together this rubber casing provides a packing betweenthe ange 13 and tliet'opedge of the member 4 by reason of which a watertight joint is formedA at this point.

The clamping member 3 is also shownas deformed to provide the `recess 15on its inner face, said recess being situated to receive the heads ofthe rivets 7 and 12 when the clamping members `are 'in closed relation.The advantage of this construction is that since the rivet heads arelocated in the recess they will not prevent the two clamping membersfrom closing tightly together. 1

It will be noted that the clamping member 3 has its lower edge24'ofl'set slightly to form a clamping flange. Then the clamping membersare closed together as shown in Fig. 5 the two side walls 5 and 6 of thepocket 1 will be rmly elampedfbe- Cil firmly clamped at their upper edgebetween the upper edge of the member 4 and the upper portion of theclamping member 3 above the recess 15 as clearly seen in Figs. 6 and 7.As stated above the recess 15 is of sufficient depth to accommodate theheads of the rivets 'l' and 12 so as to ensure this clamping action.

The flange 18 at the upper edge ofthe member 23 provides a furtherwatertightjoint between said iange and the top edge of the clampingmember 4 so that when the clamping members are closed there is nopossibility of any water leaking into the pocket.

In order to make it sure that the flange 13 will always have a watertight engage ment with the upper edge of the clamping member 4 I haveprovided said clamping member with a. lip or extension 16 which isadapted to engage the under side of the member 4 when the clampingmembers are closed. This lip prevents the clamping members from closingsutliciently to enable the end 11 of the clamping member f3 to snap pastthe spring catch 10 unless the parts are so relatively positioned thatthe lip 16 can pass underneath the lower edge of the member 4.Consequently whenever the pocket is closed the flange 13 will have awater tight engagement with the upper edge of the member 4.

A pocket having the above construction may be built into a garment ormay bc made to be worn independently of the garment. As herein shown thepocket is designed to be carried by a belt and may thus be wornindependently of a bathing suit or other garment.

The clamping member` 4 which lies on the inside next the body is shownas provided with the U-shaped extension 17 to the lower end of which oneside of the pocket member is riveted as shown at 18. rllhis extension isalso provided with two loops 19 through which a belt 2O may be threaded.The eX- tension 18 holds the pocketin shape so that when worn it willlie flatly against the body.

The pocket is absolutely water tight and may be used to hold varioussmall articles such as matches, money, either in the forml of coins orbills, jewelry, toilet articles, etc. Being independent from the bathingsuit it provides a pocket which can be worn by any one regardless of thecharacter of their bathing suits.

While I have illustrated herein a selected embodiment of my invention Ido not wish to be limited to the constructional features shown.
